BUTTER-PAC KAG E.

SPECIFICATION forming To all whom it may concern.-

Be it known that I, JAMES P. SINCLAIR, of Mottville, in the county ofOnondaga and State of New York, have invented a new and ImprovedButter-Package, of which the fol- This invention seeks to provide anair-tight package for holding small quantities of butter, which packagemay be used over and over again.

Reference is to be had to the accompanying drawings, ibrming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a broken front elevation of my new andimprovedbutter-package as it appears when the two parts of the package arelocked together. Fig. 2 is a sectional elevation of one of the jars; andFig. 3 is a perspective view of one of the wooden locking- A. Arepresent the jars. These are by preference made of glass, and areformed with the flanges a a. These flanges a a are made a little belowthe open ends of the jars, so as to form the lips I) b, for retaining inplace the rubber or other packing, B, placed between the flanges (upwhen the jars'AA are put together; and the flanges a a are beveled orformed with the enlarged portions 0 c on opposite sides of the jars, asshown clearly in Fig. 1, which enable the jars to be drawn snuglytogether upon the packing B by the locking-buttons G- C; placed upon theflanges a a, and the flanges a a are beveled or undercut, as shown at ee, to furnish a secure hold for the notches f f of the buttons 0 O. ThebuttonsOG are turned into the shape shown, and the notches f f thereofare slightly undercut to correspond with the undercut shape of theflanges a a, and at g the buttons are made concaved to correspond withthe shape of the outer edges of the flanges a a, which are slightlyrounded. as shown at a a, Fig. 1, thus making the buttons to fit nicelypart of Letters Patent No. 295,295, dated March 18, 1884. Applicationfiled September 11, 1883. Modem upon the flanges, and thus preventingall danger of the buttons, when applied and being forced upon thethickened portions 0 c of the flanges c a, turning sidewise, which wouldtend to break the flanges and to make an insecure and unreliable lock.Constructed as shown, the buttons will not slip off from the flanges andloosen the joint between the jars, nor will they break the flanges.

In use both jars. A A, will be filled with butter and then placed faceto face one upon the other, with the packing B placed between theiredges. The buttons G G will then be placed upon the flanges a a andforced upon the thickened portions 0 0 thereof, which will draw theedges of the jarsAA together firmly upon the packing B, which willperfectly eX- clude the air from the butter, thus enabling the butter tobe kept in the package fresh and sweet for a great length of time.

I am aware that it is not broadly new to form a butter-package in twosections held together on intermediate packing, or to use outercam-flanges in conjunction with the clamps which hold the sectionstightly pressed on the packing; but

What ldo claim as new and of my invention 1. The combination, with jarsA A, having the cam-flanges undercut at top and bottom, of the twobuttons 0 G, provided with correspondingly shaped notches f, whereby theclamps are held in place, as described.

2. The jars A A, formed with the flanges a a, made rounding at theirouter edges, as at a a, undercut, as at e e, and enlarged, as at c c, incombination with the buttons 0 0, formed with the undercut notches f f,and made rounding, as at g, substantially as and for the purposes setforth.
